13. Tratamento e reuso do efluente de biodigestores no processo de biodigestão anaeróbia da cama de frango / Treatment and reuse of efluent of digesters in the anaerobic digestion of poultry litter
The anaerobic digestion process contributes as a method of treating poultry litter and energy generation. However, its applicability may cause some counter-intuitive, requiring for dilution to provide a suitable environment for microorganisms active in the anaerobic process. This dilution increases volume and difficulty of disposal of effluent. Thus, the obj

15. Fabrication and characterization of nanofibrous scaffold developed by electrospinning
Electrospinning has been recognized as an efficient technique for the forming of polymer nanofibers. Silk fibroin (SF) nanofibers were electrospun from SF solution using trifluoroacetic acid solution as a solvent. In the present work, we have systematically evaluated the effects of instrument parameters, including applied voltage, tip-target distance, soluti

20. Identificação dos produtos de degradação química/eletroquímica do herbicida ametrina / Identification of degration products of chemical/electrochemical herbicide ametrine
In this study the identification of degradation products ametrina (AME), pesticides used on a large scale in the sugar industry. The improvement in the treatment of environmental conditions is of paramount importance to the agricultural regions, since the contamination of soil and groundwater contamination is almost inevitable. In relation to industries prod

22. Substratum quality indicators for revegetated areas monitoring: study directed to the sand mining. / Indicadores da qualidade do substrato para monitoramento de áreas revegetadas: estudo dirigido à mineração de areia.
Mining is an agent of significant changes in soil properties. Successful land rehabilitation depends on restoring those characteristics in natural soils or establishing a suitable substratum for plant growth using available materials such as waste rock or mineral tailings. A process for monitoring the quality of the substratum in mine-affected areas was deve
